[ABANDONED] Simple fs mock with posix and windows file system styles

fs-mock

Simple fs mock with posix and windows file system styles.

Unfortunately I don't have any more time to maintain this repository :-(

Don't you want to save me and this project by taking over it?

$ npm install fs-mock

This module does not change original fs module in any way.

If you want to pass this module into other module, you will have to use for example rewire package.

var FS = require('fs-mock');
var fs = new FS({
    'var': {},                                          // empty directory
    'var/www/index.php': '',                            // empty file in /var/www, so directory var is now not empty
    'home/david/documents/school/projects': {},
    'home': {
        'david': {},
        'john': {
            'password.txt': 'my super password'         // file
        }
    }
});
 
var myPassword = fs.readFileSync('/home/john/password.txt', {encoding: 'utf8'});        // my super password

If you write some path like this: home/david/documents/school/projects, it will be automatically expanded and all its parent directories will be also added to mocked file system.

var fs = new FS({
    'Users': {
        'David': {
            'password.txt': 'my super password'
        }
    }
}, {
    windows: true
});

This will change delimiter from / to \ and add root directory to c:.

new FS({ ... }, {
    windows: true,
    drives: ['c:', 'd:', 'z:']
});
new FS({ ... }, {
    windows: true,
    drives: ['c:', 'd:', 'z:'],
    root: 'z:'
});

Now every path will be saved into z: drive.

If you want to save paths to custom drives, you need to disable auto saving into options.root.

new FS({
    'c:': {
        'Users': {}
    },
    'x:': {
        'xampp': {
            'htdocs': {}
        }
    }
}, {
    windows: true,
    root: false
});

I haven't got any machine with Windows so all methods (like chmod) works just like in Unix systems. Please let me know if you want to improve this and how.

There are also all *Sync methods.

Calling unsupported methods will throw an exception.
